It appears Cara Delevingne might have moved on to blonder pastures. Following rumors that the 21-year-old supermodel had split from girlfriend Michelle Rodriguez, the UK native was spotted looking cozy with actress Sienna Miller this week.

According to a report from TMZ, Delevingne was photographed holding hands with Miller, 32, of “Factory Girl” fame while exiting Loulou’s club in Mayfair, London Tuesday night. Prior to their PDA-filled exit, the pair reportedly attended Kate Moss’ Topshop collection after party alongside the likes of models Suki Waterhouse and Naomi Campbell. According to UK’s The Mirror, the duo left the event to continue their night at the London hot spot without the accompaniment of their famous friends.

While the friendly duo has yet to confirm or deny relationship rumors, TMZ speculated that Miller might be trying to drive a wedge between Delevingne and her girlfriend of four months “Fast & Furious” film star, Michelle Rodriquez. “Sienna has a history of playing the role of homewrecker... so M-Rod might want to nip this thing in the bud, just in case,” reads the report.

“Cara Delevigne gets around!” reads a similar report from RumorFix.com about the duo’s hand-holding session. “We’re not sure what’s going on here, but one thing is for certain- Cara likes herself some cougar action!” quipped the gossip site.

The duo last sparked dating rumors after sharing a kiss at the Met Ball in New York in May. The model, who shared an image of their smooch on Instagram, labeled the sultry shot as “Studded love! X.”

Delevingne’s outing with Miller comes on the heels of reports that she had called it quits with Rodriguez, 35. According to a report from ShowBizSpy.com Tuesday, the duo’s highly-publicized romance recently fizzled, an insider claiming that Delevingne’s relationship with the action star was “only a phase."

“Cara enjoyed spending time with Michelle, she was more carefree about the situation, whereas Michelle was taking it very seriously,” sources revealed to the gossip site.

Despite the dating speculation, Miller is said to be currently attached to her fiancé, “On the Road” actor Tom Sturridge, 28. The pair, who have a 21-month-old daughter together, were last photographed out-and-about in London Monday.
